I'm not familiar with your camera model, but if it is similar to the L101k-2k, the following might be helpful:
Before trying anything else, upgrade to IMAQ 3.1.3. If that doesn't help, here are the next steps:
1) First, back-up your .icd file so you can revert to it if you need to later.
2) Search your .icd file for the field labeled "TermChar". For my own camera, the L101k-2k, this comes at the end of the section that defines the serial coom settings (baud rate, no. of stop bits, etc.).
The value for TermChar in the file may be "\r". "\n" or some hex value (of the format \x0N - where x0N represents the hex representation of the termination character. )
3) Next, look through your camera's documentation and determine the correct termination character. If there is a discrepancy, between the value in the .icd file and the Basler documentation, change the character and save the updated .icd file.
Alternatively, you may want to try checking for a new .icd file on the Basler web site:
If none of this helps, you may also want to try NI's Camera Configuration File Generator utility (available from NI's FTP site). This utility helped me to identify an irregularity in the command formatting for my own camera. While it didn't completely solve the problem, it helped me to find a useful workaround.
